Craftsman 917.289240
Briggs and Stratton Platinum Series 21.0 HP 540 cc Model 331877 Type 1234 B1 Code 090608ZD
Serial 090608ZD67562
Bought new in summer of 2009, and this is the first engine problem I've had with it.
Battery is dated May 2018 and has been on a BatteryMinder with microsecond pulses whenever not in use. It measured 13.5 volts when I started.
Today I tried to start it for the first time this year. The solenoid clicked, but that's all; I measured 0.0 volts at the starter motor with the solenoid engaged. Then I disconnected one end of the big wire going from the solenoid to the starter, turned the key again, and got battery voltage at the solenoid's output terminal. I took an automobile jumper cable, hooked one end to the starter motor and tapped the other end against the battery terminal; that got some action from the starter. That makes me think that the battery and the starter are OK, so it must be the solenoid. Measured the resistance from input to output terminal on the solenoid when it's engaged and got a 0.65 ohms. I don't know how that compares with what it should be.
Is there anything else I should try before starting to buy parts? I could run jumper cables from the car battery and see what happens that way.
thanks, guys all suggestions gratefully received
